UITextField attributedText
@property(nonatomic,copy) NSAttributedString *attributedText
Discussion of [UITextField attributedText]
This property is nil by default. Assigning a new value to this property also replaces the value of the text property with the same string data, albeit without any formatting information. In addition, assigning a new a value updates the values in the font, textColor, and other style-related properties so that they reflect the style information starting at location 0 in the attributed string.
UITextField attributedText example.
NSMutableAttributedString *attString = [[NSMutableAttributedString alloc] initWithString:@"Some String"];
[attString addAttribute:(NSString*)kCTUnderlineStyleAttributeName
value:[NSNumber numberWithInt:kCTUnderlineStyleSingle]
range:(NSRange){0,[attString length]}];
textView.attributedText = attString;
[attString addAttribute:(NSString*)kCTUnderlineStyleAttributeName
value:[NSNumber numberWithInt:kCTUnderlineStyleSingle]
range:(NSRange){0,[attString length]}];
textView.attributedText = attString;
